 @pepemujica the pi is nit able to use your microphone, can you test it with another one? 
- 
 @strawberry-3.141 Actually, I’ve tried whith an “Online Mic Tester” and could record and listen my voice, so I asume it is able to use the microphone. Could you recommend me something else? 
- 
 @pepemujica you could try to record on the pi https://stackoverflow.com/questions/28054731/capture-record-audio-input-in-raspberrypi 
- 
 @strawberry-3.141 I can record with the mic when I use arecord -f cd -D plughw:0 -d 10 a.wav and after I can listen 
- 
 @pepemujica the error message says that your microphone is used by something else, so i guess you have to investigate on that
